Cactus Tech Stack

Software engineering and AI consulting for Western European tech companies

IT Services and IT Consulting Ghent, Flemish Region 51–200 employees Founded 2007 Privately Held

Cactus is a 100-person Belgian software engineering shop founded in 2007, operating across full-stack development, embedded systems, and AI integration. The tech stack reveals a split identity: deep expertise in hardware-adjacent tools (Altium, MATLAB, LabVIEW, SPICE) combined with modern cloud-native infrastructure (AWS, Neon, ClickHouse, Next.js, NestJS). Active adoption of .NET MAUI, React, and Angular alongside infrastructure-as-code signals a shift toward scaling web and mobile delivery; the engineering-heavy hiring mix (6 of 7 roles) focused on senior and mid-level talent suggests they're building internal capacity rather than pure staffing.
